Hi I am new to web development and am trying to get activejdbc to connect to a cloud sql instance... I am getting the following stacktrace:

My connection string in database.properties looks like this:
development.url=jdbc:mysql://google/database?cloudSqlInstance=project:location:instance&socketFactory=com.google.cloud.sql.mysql.SocketFactory&user=dbuser&password=dbuserpassword&useSSL=false
I have used the same connection string with spring-hibernate configuration with out a problem, but would like to try activeweb-activejdbc. Why the compiler cannot find the class? I have included google cloud sql dependency in pom.xml:
<dependency>
<groupId>com.google.cloud.sql</groupId>
<artifactId>mysql-socket-factory-connector-j-6</artifactId>
<version>1.0.2</version>
</dependency>
First, you need to include a fill stack trace. Second, if you get a ClassNotFoundException, this means you do not have that class on the classpath. You need to know for a fact that the class is there. Use Maven dependency plugin, or expand all your dependent jar files and ensure you have the class. No magic here:)
UPDATE: Now that you provided the stack trace, I see that the exception happens when you run the migrator. If you look at the migrator configuration, you will see that it requires its own class path. For instance, the example here: https://github.com/javalite/activeweb-simple/blob/master/pom.xml#L39 lists the MySQL JDBC driver especially for the migrator, even if you have it configured already for the project runtime. Just copy the config, and replace the MySQL driver with your driver.
